Dual Buffer Looper

[RobotZombie23]

How would you wire it?
In>Buffer>Loop1>Loop2>Buffer>Out
Or
In>Buffer>Loop1>Buffer>Loop2>Out
Using this dual buffer I had sitting around

using the 2 inputs, 2 outputs (separate buffered lines) config.
Toggles for the Buffer and footswitch for the Loops.
I intend to run my PPCB 3 channel mixer/splitter on Loop 1 and modulation effects on loop 2

My thought would be to have a buffer on the input, before loop 1, then a buffer on the output, after loop 2. Then no matter what you run before your loops (presumably guitar in, and amp out), you're buffered.
